ScienceDaily (May 9, 2011) — Even short-term use of some painkillers could be dangerous for people who've had a heart attack, according to research published in Circulation: Journal of the American Heart Association. Researchers analyzed the duration of prescription non-steroidal anti-inflammatory drugs (NSAIDs) treatment and cardiovascular risk in a nationwide Danish cohort of patients with prior heart attack. They found the use of NSAIDs was associated with a 45 percent increased risk of death or recurrent heart attack within as little as one week of treatment, and a 55 percent increased risk if treatment extended to three months.
